Be itknown that I, BENJAMIN ILLINGwoRrH, of Freeport, in the county ofStephenson, and in the Stateo Illinois, have invented certain new anduseful Improvements in Churns; and do hereby declare that the follow- A`g drawings, and to the letters of reference -marked thereon. I* In theannexed drawings, melting port of this specification, A represents achurn-dasher, constructed substuntially in the form represented, beingprovided on its upper side with two annular grooves or recesses, E andF, from the bottoms of whichare made the holes d al and a a. Brepresents the churn-stai?, the lower end of which is made fast to thedusher A. This stalis made hollow from one end to the other. In theupper end of the hollow of the shaft is inserted a plug, D, over thelower end of which plug is first drawn an India-ruhber nipple, C. Thisnipple has a slotl in its lower end. The plug is made hollow, so that inchurning,'as the flasherl and staff rise, air is drown in the churnthrough the plug and through the slot in the nipple, and then throughthe hollow shaft. When the dnsher and stuff descend, the slot in thenipple closes, to prevent the passage of air backwards, or up und ont ofthe staii'.

This arrangement is for the purpose of introducing air into the churnduring the process of churning butter, to facilitate theoperatou.

Having thus fullydescribed my invention, what I claim as new, und desireto secure by Letters Patent,'is

The dnsher A, as constructed, used with the staff B, marie hollow, undprovidedwith the plug D and nipple Cysubstnntially as and for thepurpose set forth. i

In testimony that I claim theforegoing, I have hereunto set myvhnnd,this 2d day of July, 1867.
